Why use a no-upload image converter?
Most image conversion tools upload your files to a server for processing. This converter is different — it processes everything in your browser using the Canvas API and WebAssembly. That means instant processing with no queue, complete privacy for sensitive photos or screenshots, and no file size limits beyond your browser's memory. There are no watermarks added to your output and no signup required.
Supported input formats
JPEG (.jpg, .jpeg), PNG (.png), WebP (.webp), GIF (.gif), SVG (.svg), BMP (.bmp), TIFF (.tiff, .tif), HEIC (.heic), HEIF (.heif), and AVIF (.avif). HEIC files from iPhones are automatically decoded using heic2any. Works in Chrome, Firefox, Safari, and Edge.
Common conversion use cases
- Convert WebP to PNG or JPG for broader compatibility with older software
- Convert HEIC photos from iPhone to JPEG or PNG for sharing and editing
- Convert PNG screenshots to WebP for smaller file sizes on the web
- Convert JPG to PNG when you need transparency support
- Batch convert entire folders of images for consistent formatting
Privacy and security
Your images are processed entirely in your browser. Nothing is uploaded, stored, or tracked on any server. This makes it safe for personal photos, confidential screenshots, medical images, legal documents, or any sensitive content. The tool works offline after the initial page load.
